“The Chief” was the oldest of the Big Three, he played the most games and you won’t find any of his collegiate statistics in an NCAA record book. Robert Parish came out of Centenary College in 1975 and was drafted by three different basketball teams in three different leagues but chose to sign with the recent NBA Champions Golden State Warriors, who were already in a  bit of a decline. His college stats are unknown because of a NCAA rule named the 1.6 rule, which is like trying to get credit from ITT Tech to transfer to Stanford.
In 1980, Red Auerbach traded 2 first-round picks, including the #1 overall included to Golden State for the #3 overall(McHale) and Parish. And so began The Big Three Era.
Parish played in an NBA record 1161 games and is the oldest player to win an NBA title(as of 2015) and 3rd oldest ever to play an NBA game.
The Chief is a consultant to the Celtics organization and is a mentor and coach for the Boston big men.
